Congenital adrenal hyperplasia (CAH)

PerkinElmer's Neonatal17 a-OH-Progesterone (17OHP) assay for its DELFIA®, AutoDELFIA® and GSP® platforms platforms provides the highest standards of reliability and safety in screening for congenital adrenal hyperplasia (CAH). It is globally the most widely used assay for 1st tier CAH screening, and in 2008 theproduct was used in 47 countries.

No extraction step needed

The assay is a straightforward dried blood spot assay.  No extraction step is needed, which means savings in both total assay time and materials.

DELFIA®-technology stands for quality

The unique fluorescent properties of lanthanide chelatesare the basis for high sensitivity and low assay variation, and these features, in turn, stand for reliable and accurate 17a-OH-Progesterone measurement with low bias.

Early diagnosis for early disease/Intervention

Congenital adrenal hyperplasia is a genetic disorder affecting 1:10,000 to 1:15,000 newborns worldwide and the most severe form of the disease can lead to a life-threatening condition during the first weeks of life.  The disease is caused by enzyme defects in the steroid biosynthesis, the most frequent types being 21- and 11a-hydroxylase deficiency. In both of these the17a-OH-progesterone, a precursor for cortisol, is increased which makes its determination a useful screening method for 95% of all of the CAH cases.

PerkinElmer's Neonatal 17OHP assay is intended for the quantitative determination of 17a-OH-progesterone indried blood spot specimens as an aid in screening newborns for CAH.
